After heating a 10.00 g sample of potassium chlorate, a student obtains an amount of oxygen calculated to be 3.90 g. Theoretical

ly, there should be 3.92 g of oxygen in this amount of potassium chlorate. What is the percent error in this experiment?

Answer:

0.51 %

Explanation:

Calculated value of the amount of oxygen is 3.9 g

Theoretical value of amount of oxygen is 3.92 g

We need to find the percent error in this experiment. It is given by the difference in theoretical and Calculated value divided by theoretical and multiplying it by 100. So,

E=\dfrac{3.92-3.9}{3.92}\times 100\\\\E=0.51\%

So, the percentage error is 0.51 %.

A car initially traveling at 24 m/s slams on the brakes and moves forward 196 m before coming to a complete halt. What was the m
Marrrta [24]

Answer:

-1.47 m/s^2

Explanation:

We can use the following SUVAT equation to solve the problem:

v^2 - u^2 = 2ad

where

v = 0 is the final velocity of the car

u = 24 m/s is the initial velocity

a is the acceleration

d = 196 m is the displacement of the car before coming to a stop

Solving the equation for a, we find the acceleration:

a=\frac{v^2-u^2}{2d}=\frac{0-(24)^2}{2(196)}=-1.47 m/s^2

What factors affect the amount of potential and kinetic energy a roller coaster has
Svetlanka [38]

Answer:

As the roller coaster goes higher, more potential energy is increased in the roller coaster. Caused by gravity and the roller coaster's position, the potential energy is stored in the roller coaster. For example, this ball is at the top of a hill, where potential energy is at it's highest. Potential energy can be calculated by Potential Energy=Mass X Acceleration X Height.
